Hypervisor device and method for failure mitigation of a virtual machine

Abstract

A hypervisor device mitigates failure of a virtual machine (VM) by masking an interrupt request (IRQ) of another VM of lower priority. A hypervisor device for failure mitigation of a VM is configured to: operate a first VM; operate a second VM, where the first VM has a higher priority level than the second VM; determine an interference parameter indicating a magnitude of interference of the second VM on the first VM; and mask at least one IRQ relating to the second VM based on the interference parameter to mitigate a failure of the first VM.

Dependencies are inferred from the claim text.
